Chelsea defender Ian Maatsen has signed a contract extension at the club and joined Bundesliga side Borussia Dortmund on loan until the end of the season.
Maatsen, whose new deal will keep him at Stamford Bridge until 2026, spent last campaign at Burnley but struggled for game time after returning to his parent club.
After making 15 appearances this term, albeit with less than 400 minutes in total under his belt, Maatsen has now been sent to Germany for more game time.
The full back's previous terms at Chelsea were initially due to expire in 2025.
